The prevalence of D(u) phenotype was investigated among rhesus negative women of childbearing age (15-45 years) in Port Harcourt, Nigeria, over a period of 17 months. A total of 1,108 women were randomly sampled, out of which 1,003 (90.5%) were rhesus positive and 105 (9.5%) rhesus negative. Only one (0.95%) of the Rh-negative women was D(u) positive while 104 (99.05%) were D(u) negative (true ...

INTRODUCTION The development of anti-D antibodies results from foetomaternal sensitisation occurring in rhesus (Rh) negative blood group women who carry an Rh-positive foetus. Despite guidelines on Rh immunoprophylaxis, isoimmunisation continues to occur, suggesting that the guidelines are not being fully applied by obstetricians. This study aims to establish the adequacy of knowledge on Rh imm...

History and nomenclature The Rh system is second only to the ABO system in importance in transfusion medicine because Rh antigens, especially D, are highly immunogenic and cause hemolytic disease of the fetus and newborn (HDFN) and hemolytic transfusion reactions (HTRs). HDFN was first described by a French midwife in 1609 in a set of twins, one of whom was hydropic and stillborn, whereas the o...

We determined cDNAs of two genes that belong to the Rhesus (Rh) blood group gene family in an amphioxus species (Branchiostoma floridae) and designated them Rh-related-1 (RhR-1) and Rh-related-2 (RhR-2). RhR-1 and RhR-2 consisted of 10 and 11 exons, respectively. 3' UTR sequences of RhR-1 were shorter (220-272 bp) than those of RhR-2 (1,505-1,650 bp). CDS lengths were 1,344 and 1,476 bp for RhR...

Aims: The ABO and Rhesus (Rh) blood group systems are most important in population genetic study for transfusion purposes. This was conducted to determine the distribution of Rh groups among Congolese donors. Methods: A retrospective at National Center Blood Transfusion, over a period 5 years from January 1, 2011, December 31, 2015. included centers Brazzaville, Pointe Noire other localities gr...

TRIM5alpha is a tripartite motif (TRIM) protein that consists of RING, B-box 2, coiled-coil, and B30.2(SPRY) domains. The TRIM5alpha(rh) protein from rhesus monkeys recognizes the human immunodeficiency virus type 1 (HIV-1) capsid as it enters the host cell and blocks virus infection prior to reverse transcription. HIV-1-restricting ability can be eliminated by disruption of the B-box 2 domain....

abstract the association between abo blood groups and helicobacter pylori seroprevalence is still controversial. we aimed to study the association between abo/rh antigens and igg seropositivity in an iranian adult population for the first time. blood samples of 300 healthy young adults aging 18-30 years were collected for h. pylori antibody detection and abo/rhesus blood group antigen typing. 5...

In their native environment, gulf toadfish excrete equal quantities of ammonia and urea. However, upon exposure to stressful conditions in the laboratory (i.e. crowding, confinement or air exposure), toadfish decrease branchial ammonia excretion and become ureotelic. The objective of this study was to determine the influences of cortisol and ammonia on ammonia excretion relative to expression o...

Background: This study was conducted to determine whether type 1 diabetes mellitus (T1DM) is associated with ABO & Rhesus (Rh) blood groups. Materials and Methods: This analytical cross sectional study was carried out on 77 patients suffering from T1DM and 96 healthy children less than 18 years old referring to Yazd Diabetes Research Center from April 2018 to May 2019. The ABO blood group and ...
